Carbon-supported Ni-Mo hydrodesulfurization (HDS) catalysts were studied and compared with previously reported results obtained from alumina supports. In contrast to the latter, the nonimpregnated carbon itself behaved as an HDS catalyst. It is suggested that the carbon support functions synergistically in a sulfided state in conjunction with Mo and Ni, so that both Mo and carbon act as sulfur sinks promoting the exposure of active Ni centers. 18 refs., 3 figs., 1 tab.
